M-Audio Keystation 61 MK3 Master-Keyboard

M-Audio Keystation 61 MK3 — USB MIDI Controller for Studio and Stage

The M-Audio Keystation 61 MK3 is a 61-key USB MIDI controller engineered for both music sequencing and playing virtual instruments on Mac or PC. Built around 61 full-size velocity-sensitive semi-weighted keys, it provides a natural-feeling keybed in a chassis that's easy to fit on any desk or stage. Connection to computers, iOS devices, or hardware is simple thanks to USB power and a 5-pin MIDI output.

Standout Features of the Keystation 61 MK3

Unlike most entry-level controllers, this model combines USB-MIDI with a traditional 5-pin MIDI output, so you can drive hardware synths directly without a computer. The box includes a USB cable, software download cards, a user guide, and the comprehensive AIR Music Tech software suite (Mini Grand, Velvet, Xpand!2, TubeSynth, Electric, Bassline) for a wide palette of sounds. Mapping the transport buttons is straightforward with support for Mackie Control / HUI / MIDI protocols in major DAWs.

Keybed and Playing Feel

Semi-weighted keys strike a balance between resistance and responsiveness, making expressive playing possible.

• Keys Number: 61 — the five-octave range is suitable for most two-hand playing styles
• Keyboard Type: Semi Weighted — offers natural resistance with a faster return than fully weighted actions
• Capture your dynamics from gentle phrases to forceful accents using the full-size velocity-sensitive keys.

Connectivity and Integration

Flexible connections let the Keystation 61 MK3 adapt to any studio or live rig.

• Outputs: MIDI OUT (5-pin DIN) — control external synths and modules directly
• Inputs: Sustain Pedal (1/4" / 6.3 mm) — add piano-like sustain with an optional footswitch such as the M-Audio SP2
• USB-MIDI: Class-compliant, plug-and-play — macOS and Windows users do not need to install drivers

Physical Specs and Power

Portability and desk fit are determined by the instrument's physical properties.

• Dimensions: 995 mm × 189 mm × 68 mm — slim enough for most desks and stage rigs
• The weight of 4.1 kg means you can easily move it between setups or pack it in a gig bag.
• Power: USB bus-powered or DC 9 V, 500 mA center-positive supply — works with laptops, USB chargers, or wall adapters
• Battery Powered: No — relies on USB or an external DC adapter
